A CORPORATION OF NEW JERSEY.

MACHINE FOR OPERATING ON SHOES.

To all whom it may concern:

Be it known that I, FREDERICK H. PERRY, a citizen of the United States, residin at Beverly, in the county of Essex and tate of Massachusetts, have invented certain new and useful Improvements in Machines for Operating on Shoes; and I do hereby declare the following to be a full, clear, and. exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to machines for operating on shoes, and more especially to means for supplying oil to the work guldes of such machines.

For rough rounding and channeling the soles of shoes, machines have heretofore been provided with devices for supplying oil to the work guides when doing certain classes of work. The supply of oil to these devices has usually been controlled by a manually adjustable valve which may be manipulated by the operator to regulate the flow of the oil or to shut off the supply in case the use of the oiling devices is to be discontinued. With these constructions, the flow of oil is continuous. An undesirable quantity of oil is liable to acciunulate on the guide between operations on successive shoes, or to accumulate and drop off onto other parts of the machine, or onto the bench in case the operator neglects to shut off the oil supply when he discontinues the use of the machine for any considerable period.

It is accordingly the object of the present invention to provide a novel and improved oiling device which will not be open to the objections outlined and which will avoid any undesirable accumulation of oil without requiring care or attention on the part of the operator. To this end the invention contemplates the provision of means actmg automatically to shut off the supply of oil to the work guides of a shoe machine between operations on successive shoes. In embodying the invention in a rough rounding and channeling machine, provided with a forepart guide which is thrown into and out of operation during the rounding and channeling of each shoe, it is preferred to control the flow of oil from the fore-part guide or its operating m hanism so that the oil is sup- Specification of Letters Patent.

plied during the time that the fore-part guide is in operation, and is shut oil when the fore-part guide is thrown out of action.

The features of the invention will be readily understood from an inspection of the accompanying drawings and the following detailed description of the mechanism illustrated therein.

In the drawings, Figure l is asectional elevation showin so much of a rough rounding and channellng machine as is necessary to illustrate the application of the present improvements thereto; and Fig. 2 is a detail front view showing the crease guide and a part of the oiling device in section.

In the drawings, the invention is shown as embodied in a rough rounding and channeling machine having the construction fully shown and described in the patent to Perry, No. 1,030,606, granted June 25, 1912. In the construction shown, 1 is the crease guide which guides the shoe during the operation upon the shank, and 2 is the fore-part guide which guides the shoe during the operation about the fore-part. The fore-part guide is carried by an arm 3 secured to a rock shaft 4 and the guide is thrown into and out of operation during the channeling and rounding of each shoe through an arm 5 secured to the shaft 1 and connected through a link 6 with a treadle, as fully illustrated in the patent above referred to.

The mechanism for supplying oil to the crease guide 1 comprises a valve casing 7 secured to the frame of the machine and.

provided with an oil passage 8 which is in communication with an oil tank or other source of oil supply through a tube 9. The casing 7 is also provided with a valve chamber 10 which communicates with the passage 8 through a port 11, and also communicates with a second valve chamber 12 through a port 13. An adjustable regulating valve 1.4 is arranged in the valve chamber 12- and is provided with a conical lower end which fits within a tube 15 projecting from the lower end of the valve chamber. The tube carries a wire 16-, the lower end of which bears against the side of the crease guide 1 and delivers the oil to the crease guide. By adjusting the Valve 14, the flow of oil to the ease guide may be ree l atel-v The supply of oil to the valve chamber 12 and to the crease guide is normally shut off by a plunger valve 17 mounted to slide in the valve chamber 10 and held from rotation by a pin 18 which extends through a slot 19 formed in the plunger. The front end of the plunger is provided with a pas sage 20 which extends longitudinally of the plunger and communicates with a port 21 formed in the upper side of the plunger. The plunger is held in normal position bv a spring 22. l/Vhen in this position, the cylindrical portion of the plunger in front of the port 21 closes the port 11 and shuts off the communication between the oil supply passage 8 and the valve chambers 10 and 12. The rear end of the valve plunger 17 is arranged in position to be engaged by the arm 5 through which the fore-part guide is thrown into and out of operation.

When the fore-part guide is out of opera tion or in the position shown in Fig. 1, the valve 17 shuts off the oil supply. When the shaft 4 is rocked to move the fore-part guide down into position to engage the shoe, the arm 5 forces the plunger valve 17 forward bringing the port 21 into register with the port 11, and thereby opening communication between the valve chambers and the oil sup ply so that the oil flows into the valve chambers and is delivered onto the fore-part guide. VJhen the fore-part guide is raised in passing from the fore-part to the shank of the shoe, the arm 5 moves back into the position indicated in Fig. 1, nd theplunger valve is returned to normal position, thus shutting off the oil supply. The valve remains in this position until another shoe is introduced into the machine and the forepart guide is again moved down into position to engage the shoe.

With this construction, the valve 17 acts to automatically shut off the oil supply when there is no shoe being operated upon. and the valve is opened and closed during the operation upon each shoe without requiring any additional care or manipulation on the part of the operator. A proper supply of oil to the crease guide during the operation upon each shoe is thus insured, and the un desirable accumulation of oil upon the crease guide, and the dripping of oil from the guide onto the bench, or onto work lying thereon between the periods when the shoe is being operated upon by the machine is prevented.

and modified to best suit the construction of the machine in which it may be embodied without departing from the broader features of the invention.

Having explained the nature and object of the invention and specifically described one form of mechanism in which it may be embodied, what I claim is 1-. A machine for operating on shoes, having, in combination, rounding and channeling mechanism including work guiding devices, means for supplying a lubricant to the workengaging surface of said devices comprising a valve normally shutting off the supply of lubricant, and means for automatically and temporarily opening the valve in operating the machine to round and channel the shoe and for closing it between successive operations.
